Longiflorum×Asiatic hybrid lily plant named `Ceb Glow`

ABSTRACT

A new and distinct lily hybrid named `Ceb Glow` characterized by upright, large, vibrant yellow flowers on tall, strong stems excellent for cut flower production.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of lilyhybrid, referred to commercially as a Longiflorum-Asiatic Lily Hybrid,referred to by the cultivar name `Ceb Glow`.

This invention is the product of a controlled breeding program inAurora, Ore. The seed parent was GH-403, a proprietary non-releasedplant. The pollen parent was AM #2, another proprietary non-releasedplant.

The longiflorum-Asiatic cross is relatively new to the trade. This typeof cross was originally made to create colored Lilium longiflorumhybrids. Instead, due to the difficulty in crossing back to L.longiflorum, the plants that were developed had to be crossed withAsiatic lilies. As such, the results look more like Asiatic lilies. Theresulting hybrids often have several advantages, not necessarily incombination, over an Asiatic lily: (1) often larger flowers; (2) oftenlarger, waxier leaves; (3) hybrid vigor; (4) lower susceptibility toscorch; (5) excellent flower texture and substance; (6) more virusresistance; (7) new and clearer colors; and (8) stronger, sturdierstems.

This invention has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity, and day length,without, however, any variation in genotype. The following traits havebeen repeatedly observed in asexually propagated progeny and aredetermined to be the basic characteristics of this invention which incombination distinguish this lily as a new and distinct cultivar: (1)large, upright vibrant yellow flowers with a white eye and some maroonspots; (2) large yellow buds; (3) tall, strong stems for cut flowers;(4) excellent vase life and (5) good vigor. Bulbs of this plant may beprecooled and forced out of season for very uniform cut flowerproduction.

To the inventor's knowledge, there are no other longiflorum-Asiatic lilyhybrids with this color flower suitable for cut flower forcing on themarket. Compared to my other new variety, `Ceb Sun`, `Ceb Glow` hasshorter stems, narrower tepals, smaller more numerous leaves, smallerbuds and flowers, and an earlier bloom time.

Asexual reproduction of this new variety has been initially andsubsequently accomplished at Cebeco Lilies, Inc. in Aurora, Ore., byscaling and tissue culture. The resulting plants have shown that theabove-mentioned unique features are stable and reproduce true to type ineach successive propagation.

DESCRIPTION OF THE DRAWING

FIG. 1 is a photograph showing the `Ceb Glow` lily.

FIG. 2 is a close-up photograph which illustrates in greater detail asingle flower of the new plant.

The photographs of the drawing were taken in August 1993 in a studio andillustrates the typical flower and foliage form, with color being astrue as is reasonably possible in this type of color photograph.
